Fractional laser skin rejuvenation

The constant development of laser technologies and the simultaneous search for the most effective and safest methods of skin renewal and rejuvenation have led to the invention of a truly revolutionary technology - fractional delivery of laser radiation.

The main advantage of this technology in comparison with its predecessors is the possibility of a deeper penetration of the laser under the skin and its uneven (fractional) effect on it, which significantly speeds up the healing process, reduces the risk of infection and reduces the likelihood of post-traumatic hyperpigmentation.

Constant improvements to fractional technology, in turn, have combined its significantly higher safety with the incredible efficiency of a carbon dioxide laser (CO2 laser). This is how the fractional CO2 laser appeared. Thanks to its creation, it became possible to predict the safety and effectiveness of the required treatment, which previously faced certain difficulties.

Effects of Fraxel CO2 laser

At present, the use of the latest fractional technologies (in particular, the Fraxel CO2 apparatus) allows for a short period of time to eliminate many skin defects that cause inconvenience and form various psychological complexes.

Thanks to the Fraxel apparatus and under the direct supervision of cosmetology specialists, now you also have the opportunity to improve the condition of your skin:

Before and after fractional laser exposure to facial skin
  • Completely get rid of stretch marks, stretch marks and all kinds of cicatricial changes on the skin (hyper- and hypotrophic), or reduce their visibility as much as possible.
  • Return the smoothness of your skin by removing the effects of acne (post-acne).
  • Achieve better skin relief by shrinking noticeably enlarged pores.
  • Remove deep and fine wrinkles in various zones.
  • Visibly rejuvenate the skin in age-sensitive areas such as the neck, décolleté, eyelids and hands.

Main advantages of fractional laser (CO2 fraxel)

Fractional laser (CO2 fraxel) is more efficient than other laser processing methods for several reasons at once:

  • It is possible to control laser damage to the skin, the damage itself is noticeably less.
  • Skin regeneration is noticeably faster.
  • The best effect is achieved due to deeper laser penetration.
  • The pain of the procedure is noticeably less, which makes it possible to use lighter methods of anesthesia (skin cooling is used during the procedure to reduce sensitivity to pain)

Principle of action of fractional laser (CO2 fraxel)

When exposed to a fractional laser on the skin, hundreds of microcoagulation treatment zones (MLZ) are formed - micro-wounds up to 3 mm deep and 100 microns in diameter, which are surrounded by healthy, intact tissue. It is due to healthy and intact skin that the MLZ regeneration process takes place - in a short time, the basal layer of the epidermis is restored. Further, the epidermis and dermis are restored - in place of the MLZ, areas of completely new, young and healthy skin are very quickly formed. No more than 20% of the skin is exposed during this procedure, which ensures its high safety. After several treatments, you will be impressed with the result!

Effects of Fractional Laser on Skin

Innovative technology of fractional laser skin rejuvenation

Innovative cosmetology technology of fractional laser resurfacing (ablative and non-ablative) allows to achieve the effect of skin rejuvenation, close to that of the traditional laser ablation technique, while being significantly less traumatic. The key advantages of the technology are the significant reduction in the rehabilitation time and the number of side effects.

What is fractional thermolysis?

The process of directing a light source to affect a selected problem area of the skin for its superficial destruction is called selective photothermolysis ("thermolysis" - destruction by thermal exposure and "photo" - using a light source).

Unlike traditional selective photothermolysis, which covers continuous areas, laser fractional thermolysis acts in fragments, creating a fine dotted mesh on the surface of the treated skin area and leaving the areas outside the mesh intact. Thus, there is a fractional (fragmentary) destruction of the problem area with a laser. This allows the patient's skin to recover from the procedure much faster than with traditional continuous exposure.

Fractional thermolysis is a fragmentary destruction of problem areas of the skin by high-intensity laser exposure, which is converted into thermal energy.

Fractional Laser Beams

Fractional laser resurfacing is ideal for effective treatment of skin problems and minimal recovery time.

Fractional laser resurfacing can significantly improve the condition of skin that is problematic from a dermatological or cosmetological point of view. Fractional laser attachments provide the most effective way to treat acne, reduce the appearance of scars, scars, wrinkles, remove age spots, chloasma, lighten and even tone, skin rejuvenation, face and neck tightening.

Principles of Fractional Laser Therapy

During the passage of the head, high-intensity laser radiation comes into contact with the skin and is converted into heat energy. The fractional laser acts fragmentarily, "burning" a fine mesh in the form of an ordered dot matrix on the skin surface. Each dot is formed by the application of one or more high-energy laser pulses. In depth, the effect of the laser can reach the dermal layer, forming cylindrical “mini-wells”. This causes the skin surface to shrink within minutes.

During the healing process, the production of new collagen in the deep layers is stimulated, the skin acquires firmness, firmness, smoothness and elasticity, looks more even and youthful.

Thus, fractional laser therapy is the most advanced cosmetological approach to skin resurfacing, a technology that uses a point effect, when treated areas are alternated with untreated ones. This ensures quick healing and reduces the risk of side effects.

Fractional Laser Skin Resurfacing Techniques

Currently, the following fractional laser resurfacing techniques are used in hardware cosmetology.

Fractional non-ablative skin resurfacing

A lightweight procedure that provides coagulation of the treated skin areas. Fractional non-ablative resurfacing does not require expensive preparation, but provides an excellent cosmetic effect with minimal redness and swelling.

Fractional Ablative Skin Resurfacing

Deep resurfacing of the skin, which makes it possible to control the depth of ablation and recovery time, depending on the power of the impact. The results are comparable to those of the traditional CO2 laser resurfacing technique, but the procedure is less painful, has fewer complications, and requires a shorter recovery period.

Combined fractional ablative and non-ablative skin resurfacing

There are techniques for combining fractional ablative and non-ablative resurfacing in one procedure. The combined approach makes it possible to flexibly adjust the depth of penetration of the laser beam, apply coagulation or ablation, depending on the problems to be solved in different types of zones. The technique helps to maximize the effectiveness of treatment and rejuvenation, while minimizing the recovery period.

Fractional thermolysis uses advanced technology to emit a laser pulse that acts on the skin for a very short time. Patients feel only tingling and tingling, no bleeding.

The diameter of each laser pulse application point (ablation point) is less than 0. 1 mm. The pinpoint injury caused by the laser is very small and heals very quickly. Due to the fact that the main part of the treatment area remains unaffected, the patient can use decorative cosmetics within a few days after the procedure.

Treatment of the entire surface of the facial skin with a fractional laser can be carried out within 20-30 minutes. and does not require hospitalization and long break in work. Therefore, fractional thermolysis is the most effective treatment and skin rejuvenation program for busy people.

Compared to erbium laser resurfacing (2940 nm), fractional thermolysis has 2 advantages associated with a greater depth of impact (tissue stimulation) and a shorter treatment duration.

Contraindications to the use of fractional lasers

  • scarring process disorders
  • phototypes V and VI
  • pigmentation disorders
  • recent use of 13-cis retinoic acid
  • mental illness

Side Effects

The use of fractional lasers gives less than 3% of side effects, which is significantly lower than the corresponding figures for ablative non-fractional lasers. Side effects include:

  • Hypertrophic scar or keloid scar (unlikely)
  • Miliums (on seborrheic skin types)
  • Hyper- or hypopigmentation (depending on the phototype and individual predisposition)
  • Infection (very unlikely due to anti-herpes prophylaxis)

How the procedure goes and what you should be prepared for after fractional rejuvenation

  • The total time of the procedure, taking into account the preparation, will take 1-2 hours. You need to plan your visit in advance.
  • The total rehabilitation time after the procedure, depending on the type of problem, ranges from 7 to 10 days.
  • Come at least 10-15 minutes before the start of the procedure.
  • The room in which the procedure is carried out has already been prepared according to the standards of the laser operating room, it remains to prepare you.
  • Before resurfacing, the face is cleansed: washing with a soft gel, rubbing with a soothing lotion.
  • For the resurfacing to be comfortable, we will have to administer local anesthesia. Taking pain relievers is recommended.
  • If you are worried, it will be comfortable if you take sedatives in advance. Sometimes, if you have had allergic reactions before, antihistamines are needed. Be sure to discuss these issues with your doctor.
  • The doctor will apply an even layer of anesthetic cream under the occlusion to the areas of the skin that will be exposed to laser exposure. The duration of anesthesia is 30-60 minutes, depending on the type and volume of laser work.
  • Then the cream is removed and the face is wiped with a special lotion. We are now ready for laser skin resurfacing.
  • The process of face resurfacing itself takes 20-30 minutes. During the procedure, the skin cooling system built into the device is used. But you can always ask the doctor to apply a cooling dry gel to the treatment area.
  • After the procedure, the doctor can apply a soothing cream, sometimes we use special lotions. Then we also use a special moisturizer.
  • Now you can go and enjoy the result. No problems or complications! But the doctor will definitely give you an emergency phone number, just in case.
  • Follow up with a doctor one week after resurfacing. He will assess the condition of the skin after treatment, you will plan further care and the time for the next procedure.

Recommendations before the procedure

  • You cannot sunbathe a month before the procedure and a month after it. And 2-3 weeks before the first procedure, start using sunscreen.
  • Your skin phototype matters! People with darker skin (IV-VI) may be less able to tolerate laser exposure, or achieve less pronounced effect. You may need to use whitening creams in this case.
  • Take a phototype test at a preliminary consultation.
  • If you are undergoing laser resurfacing for acne, keep the following in mind:
    • Taking photosensitizing drugs is excluded.
    • If you are taking or have taken systemic or at least local retinoids, be sure to inform your doctor about it. Laser treatments may be contraindicated for you.
  • After the procedure, within a week, you will need special care, it must be selected individually together with the doctor.
  • Sometimes a skin preparation, such as a TCA peel or retinoic peel, is recommended 3 weeks before the laser procedure.
